Ecology and Classification of North American Freshwater Invertebrates

Summary: Excellent support for benthic macroinvertebrate surveys
Review: A retired chemist, I have been using Thorp and Covich in connection with benthic macroinvertebrate surveys related to stream water quality work. The drawings are extremely clear, and the keys are excellent. As an amateur, I particularly appreciate the book's comprehensive glossary. If you find that Voshell's fine but brief Guide to Common Freshwater Invertebrates of North America does not provide you with the level of detail you need, you'll almost certainly find Thorp and Covich very useful. A minor flaw--the page(s) listed in the index for an item are often three pages earlier than the page(s) in the book at which the item actually occurs.

Summary: Excellent macroinvertebrate reference book
Review: I found this book to be an excellent reference source for me as a field biologist. The chapters contain background information for each family along with drawings and a chapter outline. I can compare the specimens I've collected to the drawings and descriptions in the book with confidence. A very useful reference for the field biologist.

Summary: A Good bench reference for non-insects
Review: The other reviewers' descriptions are correct: this is a valuable reference. I would like to like to clarify this a little however. The text is an important tool for taxonomists and ecologists working with aquatic macroinvertebrates. However, its emphasis is clearly on non-insects. If you need to identify insects-the most abundant aquatic macroinvertebrates, you should use Merritt and Cummins (1996) text: An introduction to the Aquatic Insects of North America. If you will be identifying samples for stream bioassessments you will need both of these books-and probably some others-as bench references.

To use these references to identify organisms, you will need access to a laboratory because you will need glassware, forceps, microscopes and other tools and chemicals. Sometimes a dissecting scope is required. Sometimes you will need to mount parts of organisms on microscope slides to view them on a compound scope at high magnification. If you represent a volunteer group and don't have access to (or experience with) this type of equipment, this book may not be for you. You might be better off with Resse Voshell's book: A Guide to Common Freshwater Invertebrates of North America. His text generally has family-level taxonomy based on characteristics observable in the field. Both books contain interesting ecological information in addition to taxonomic identification.

So yes, this book clearly deserves two "Thumbs Up" but you should consider your experience level, taxonomic need, and how you will use this book before you purchase it. I hope this helps you decide if the book is right for you. Feel free to email me with questions if necessary ([e-mail]). Best regards.

Summary: A Major Source of Aquatic Invertebrate Information
Review: The second edition of "Ecology and Classification of North American Freshwater Invertebrates" has provided aquatic biologists with a powerful tool. The study of freshwater organisms has gained in importance as we see our precious water resources become more scarce and polluted. As water flows downhill it takes with it every chemical and waste product we deposit on the surface. Fresh water (and marine) organisms are a first line of defense alerting us to the destruction. The presence or absence of many of these organisms is often significant in regard to water quality and environmental health.

In addition, there is increased interest in our freshwater systems and their biota, both among professionals and knowledgeable amateurs. The lack of funding and specialists in certain areas for the needed research in aquatic systems may make the role of the latter more important with time, as has already occurred in astronomy and to a lesser degree in other areas of study.

This book is a good summery of aquatic organisms from Protozoa to Arthropoda. Despite a few irritating typos, it compares well with earlier editions of Pennak's "Freshwater Invertebrates of the United States" in coverage (the 4th edition of Pennak drops both the protoctists and the insects, while retaining the non-insect arthropods and including some color illustrations). If one can afford them they are both worth having, but for reasonably up-to-date overall coverage and inclusiveness and at a cheaper price, Thorp and Covich (eds.) book is a good reference for all Canadian and U. S. freshwater invertebrates in the very broad sense.
